IMPROVEMENT IN DEVICES FOR SEALING JARS.

Specification forming part of Letters Patent No. 211,141, dated January7, 1879; application filed November 1, 1878.

To all whom it may concern.-

Be it known that I, EMILE FETARD, of G0- nesse, France, have invented anew and use ful Improvement in Sealing Jars; and I do hereby declare thefollowing, when taken in connection with the accompanying drawings andthe letters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of thisspecification.

My invention relates to an improvement in the devices for sealing jarsfor various purposes, which, as here represented, is designed for thetransportation of milk.

My invention bears chiefly on the system of closing; and it consists inmeans of securing on the milk-vessel which is generally of earth enware,a lid or cover likewise in earthenware. Thislid is kept firmly closed bymeans of a crossbar which presses it down through a spring, and which isitself fixed by a loop on a staple secured to the vessel, this staplehold-,

ing the cord which is sealed with lead.

Such is the substance of the closing arrange ment applied to themilk-vessel shown in the annexed drawings, whereby the manner ofperforming my invention may be understood.

Figure l is partly an elevation and partly a vertical section of thevessel and Fig. 2 a plan.

The vessel to is generally made of earthenware, and is of the usualshape with only its upper part modified. It terminates, as usual, with aprojecting lip, below which I lit a ring b, of tinplate soldered. Thisring has two eyes, 5 b, to which is hooked the bow=handle c. It has alsothe eye 0 and staple f. These four appendages are cast or soldered onthe ring.

The earthenware disk (I, which forms the lid or cover, is provided witha central rod, 19, carryin g the helical spring g, which is kept on bythe collar at the endof the rod 19. A flat bladespring might besubstituted for the helical spring, the function in either case being torender elastic the pressure exerted-b y the locking-bar h. A washer offabric, rv,makes the joint tight under the lid d.

The bar h of cast or malleable iron has in its middle a hole, 0, for thepassage of the head of the rod 1?, and bears directly on the spring. Itsends are bent to the form of rings, one, i, jointing with the eye 0projecting from the ring I), and the other, j, jointing with one end ofthe loop 70. The latter by its hole Z engages on the staple f projectingfrom the ring b.

The various pieces combined, as shown, act as follows in the opening orclosing of the vessel. For closing it the lid cl is put on the mouth ofthe vessel along with the bar h, which is connected to the lid. B-ypressing down the bar the spring is sufficiently compressed to permitthe loop 70 to engage on the staple f. It then onlyremains to'pass thecord through the eye 1" of the staple, and to join its two ends by thelead.

I claim- The combination of the jar a, ring 1), pro vided with eyes 1),eye 0, and stop f, handle 0, the disk or. cover d, locking-bar h, hingedto the eye a, the loop k, and spring g, all as shown and described.

In testimony whereof I have signed my name to this specification beforetwo subscribing witnesses.
